Tons of women by the Brazilian Blowout, but Mary Louise Parker? Not so much.

In an interview with T magazine, the Weeds star was asked about beauty mishaps and the hair straightening treatment is one of them.

She explains:

"Yes. Not trusting my instincts — letting my vanity take over — and having the Brazilian Straightening Treatment. I’ve experienced hair fall-out in the past, and it is not fun. This treatment resulted in more. My advice: don’t do it!"
